Method of making magneto-acoustic markers with amorphous alloys in electronic article surveillance having reduced, low or zero Co-content and marker obtained |
摘要 |
<p>A ferromagnetic resonator for use in a marker in a magnetomechanical electronic article surveillance system is manufactured at reduced cost by being continuously annealed with a tensile stress applied along the ribbon axis and by providing an amorphous magnetic alloy containing iron, cobalt and nickel and in which the portion of cobalt is less than 3 at%.</p> |
